Flow-diverter stents combined with flow-T stenting-assisted coiling for the treatment of a large basilar apex aneurysm: a case report with a 9-month follow-up.

Background: Endovascular or surgical treatment of wide-neck, large basilar apex aneurysms is challenging. We present a novel concept for the treatment of complex basilar apex aneurysms using flow-diverter devices combined with the flow-T stenting-assisted coiling technique. Assess the efficacy and safety profile of the technique in this complex aneurysm. Case description: A patient with multiple unruptured intracranial aneurysms underwent staged treatment. A large basilar apex aneurysm was treated with a flow-diverter stent combined with a flow-T stenting-assisted coiling technique in the first stage, and a giant supraclinoid aneurysm was treated with a flow-diverter stent applied in the second stage. Clinical presentations, technical details, intra- and perioperative complications, and clinical and angiographic outcomes were recorded, with a 9-month follow-up. Results: The patient achieved full neurologic recovery postoperatively. Cerebral angiography performed postoperatively showed revascularization, good laminar flow, and no in-stent or adjacent stenosis. Conclusion: Flow-diverter stents combined with flow-T stenting-assisted coiling for the treatment of giant basilar apex aneurysms is a feasible technique with efficacy demonstrated at a 9-month follow-up. Staged endovascular treatment of multiple intracranial aneurysms may be a safe and viable option.

Association between childhood physical abuse and suicidal behaviors among Chinese adolescents: The mediation of aggression.

BACKGROUND: Although previous studies have examined many predictors of suicidal behaviors. However, little is known for childhood physical abuse (CPA) and aggression, which are prevalent among adolescents. This study aimed to explore association between CPA and suicidal behaviors, and the potential mediating role of aggression. METHOD: A total of 16,111 students graded 7 to 12 were recruited using a stratified cluster sampling across five representative provinces in China. Conflict Tactics Scale-Parents to Child (CTS-PC) and Buss and Warren's Aggression Questionnaire (BWAQ) were used to measure CPA and aggression, respectively. RESULTS: During the last year, 16.0 % of adolescents reported suicidal behaviors. Specifically, 7.9 % were suicide ideators, 4.6 % were planners, and 3.5 % were attempters. The prevalence of CPA in mild, moderate, and severe was 15.7 %, 26.9 %, and 4.4 %, respectively. Multinomial logistic regression indicated that moderate and severe CPA and overall aggression were associated with suicide ideators, planners, and attempters. In five sub-types of aggression, only hostility was significantly associated with all three suicidal behaviors. Structural equation modelling showed that aggression partially mediate the relationship between CPA and suicidal behaviors. The mediation proportion of overall aggression, physical aggression, verbal aggression, anger, hostility, and indirect aggression were 27.2 %, 22.4 %, 5.2 %, 14.2 %, 23.5 %, and 12.1 %, respectively. LIMITATIONS: Cross-sectional design, self-reported questionnaire, and no other forms of childhood maltreatment. CONCLUSIONS: CPA is a critical risk factor of suicidal behaviors among Chinese adolescents and aggression is a mediator between CPA and suicidal behaviors. Targeted suicide prevention should focus on those adolescents who report CPA and aggression, especially for hostility.

Identification and Verification of Immune Subtype-Related lncRNAs in Clear Cell Renal Cell Carcinoma.

Background: According to clinical study results, immune checkpoint blockade (ICB) treatment enhances the survival outcome of patients with clear cell renal cell carcinoma (ccRCC). Previous research has divided ccRCC patients into immune subtypes with distinct ICB response rates. However, the study on the association between lncRNAs and ccRCC immune subtypes is lacking. Methods: Differentially expressed lncRNAs/mRNAs between two major immune subgroups were calculated. A weighted gene co-expression network analysis (WGCNA) was conducted to establish the lncRNA-mRNA co-expression network and select the key lncRNAs. Then, prognostic lncRNAs were selected from the network by the bioinformatics method. Next, the risk-score was estimated by lncRNA expression and their coefficients. Finally, a nomogram based on lncRNAs and clinical parameters was created to predict the prognosis of ccRCC. Results: LncRNAs and mRNAs associated with ccRCC immune subtypes were identified. The lncRNAs and mRNAs from a gene module closely linked to the immune subtype were used to construct a network. The KEGG pathways enriched in the network were related to immune system activation processes. These 8 lncRNAs (AL365361.1, LINC01934, AC090152.1, PCED1B-AS1, LINC00426, AC007728.2, AC243829.4, and LINC00158) were found to be positively correlated with immune cells of the tumor microenvironment. The C-index of the nomogram was 0.777, and the calibration curve data suggests that the nomogram has a high degree of discriminating capacity. Conclusion: In summary, we discovered core lncRNAs linked with immune subtypes and created corresponding lncRNA-mRNA networks. These lncRNAs are anticipated to have predictive significance for ccRCC and may provide insight into novel biomarkers for the disease.

Sex differences in association between Internet addiction and aggression among adolescents aged 12 to 18 in mainland of China.

BACKGROUND: Previous studies have reported that Internet addiction (IA) is an important predictor of aggression. However, little is known whether aggression is a risk factor of IA. This study aims to explore whether IA can predict total and sub-types of aggression, whether aggression also can predict IA, and the potential sex difference. METHOD: A total of 15,977 adolescents aged 12 to 18 were recruited though a stratified cluster sampling across five representative provinces in mainland of China. Young's Internet Addiction Test (IAT) and Buss and Warren's Aggression Questionnaire (BWAQ) were used to measure IA and aggression, respectively. RESULTS: The prevalence of IA and total aggression was 16.8 % and 25.0 %, respectively. Binary logistic regression analysis indicated that IAT score was significantly associated with total and five sub-types of aggression (P < 0.001). However, scores of physical aggression, hostility, and indirect aggression were positively associated with IA (P < 0.001), while verbal aggression and anger were not significant (P > 0.05). Moreover, the interaction of sex and IA was significant for aggression. Specifically, females with IA had higher risks of anger and indirect aggression but had lower risks of physical and verbal aggression compared to males with IA. LIMITATIONS: Cross-sectional design, self-reported information, and only Chinese rural adolescents. CONCLUSIONS: IA is a strong risk factor of total and five sub-types of aggression, while not all sub-types of aggression are predictors of IA. Prevention programs for adolescents' IA and aggression should consider different aggression sub-types and sex.

Potential markers for predicting delayed encephalopathy in patients with acute carbon monoxide poisoning.

BACKGROUND: Acute carbon monoxide poisoning (ACOP) commonly results in delayed neuropsychiatric sequelae (DNS). Currently, there are no reliable predictors. The aim of this article is to establish a practical model for predicting the development of delayed encephalopathy clinically. METHODS: Retrospective analysis of clinical data were performed at a single institution for the past 6 years. 107 patients with ACOP were recruited, of who 67 developed DNS and 40 did not. Clinical characteristics of the patients were analyzed between the two groups. The risk factors associated with DNS development were screened to identify the potential markers for predicting DNS. A predictive model was then built, and the receiver operating characteristic (ROC) curve analysis was used to assess its predictive ability. RESULTS: There were significant differences in 13 clinical features between the two groups. Four potential markers were identified. They were age, source of CO, Glasgow Coma Scale score and the initiation of HBOT. The potential predictive model showed an area under the curve (AUC) of 0.93 in the training set and 0.97 in the testing set. CONCLUSIONS: Our model could calculate the probability of DNS after acute CO poisoning.

Monitoring of the Effect of Cerebral Autoregulation on Delayed Cerebral Ischemia in Patients with Aneurysmal Subarachnoid Hemorrhage.

OBJECTIVE: To detect cerebral autoregulation (CA) in patients with aneurysmal subarachnoid hemorrhage (aSAH) by near-infrared spectroscopy and to assess its association with delayed cerebral ischemia (DCI). METHODS: From January to August 2017, 81 patients (average age 53.25 ± 10.27 years) were studied. Near-infrared spectroscopy was used to monitor CA, and associated factors were evaluated. Monitoring of CA was carried out at 5 time points (preoperative day 1 and postoperative days 1, 2, 3, and 7). Patients were sorted into 2 groups according to whether DCI occurred (DCI group and non-DCI group). The relationship between CA and DCI in patients with aSAH was analyzed. RESULTS: Among 81 patients, CA trended toward being impaired in patients with aSAH with a poorer grade. DCI occurred in 39 of 51 (48.15%) patients with impaired CA. DCI occurred in 6 of 30 (7.4%) patients with intact CA. CONCLUSIONS: Impaired CA monitored by near-infrared spectroscopy was shown in patients with aSAH before and after surgical intervention. Older age, smoking, hypertension, and especially impaired CA are independent risk factors for patients with DCI.
